“…As no additional pressure was applied onto the specimens during diffusion bonding process, the specimens could be bonded only when temperature was higher than 900 °C. This finding is slightly different from those reported previously, which showed that good bonding could form at much lower temperatures when much higher pressures were applied and maintained throughout the bonding process [6][7][8][9].

“…A number of studies have been reported on diffusion bonding of Ti or Ti-alloys to steels [6][7][8][9] and the bond strength between Ti and steel is found to depend on the microstructure formed in the interfacial region, which are affected by processing conditions, steel composition and interlayer metal used in the process. However, there have been no reports on the feasibility of hot-rolling such diffusion bonded Ti-clad steels to plates of different thicknesses.…”

Abstract. Ti was diffusion-bonded to a grade of carbon steel containing about 0.13 wt% C. The diffusion-bonded specimen was then hot-rolled to a final reduction in thickness of about 71 %. There were no delaminations during hot-rolling. The cross sectional microstructures of specimens before and after hot-rolling were characterised using scanning electron microscopy, energy dispersive spectroscopy and optical microscopy. It was proved that it is technically feasible to produce Ti-clad carbon steel plates using a process of diffusion bonding followed by hot-rolling. It was also demonstrated that normal heat treatment procedures involving quenching and tempering can be applied to Ti-clad carbon steels after hot-rolling. The bond strength of the claddings would be determined by the intermetallic compound phases formed at the interface between Ti and carbon steel, which could be optimised by adjusting the conditions of diffusion bonding and hot rolling processes.

“…The determined Cr peak in the line-scans (barely visible at 750 and 850 8C; clearly visible at 865 and 950 8C) corroborates the conclusion that diffusion of Ti into the stainless steel decreases the activity of Cr. [6][7][8] The diffusion takes place down the activity gradient, rather than the concentration gradient, which results in an uphill diffusion of Cr.…”

Cold roll bonding of dissimilar metals (two or more material layers) is a well-known, cold, pressure-welding process and provides great advantages in comparison to single alloys for a variety of applications. It allows various material properties (optical, mechanical, thermal, chemical or electromagnetic) to be combined, which a single material cannot achieve. One example for the application of this technique is the bonding of wear-resistant parts where a high-strength material is bonded onto softer base materials. Depending on the requirement, 3 or 5 layers are no rarity. The manufacturing industry faces the challenge of increasing demands on material characteristics, which can only be satisfied by developing new clad material combinations. In this first of two papers, diffusion phenomena of alloying elements and the corresponding interface-layer formation are the focus of the investigation. In a further paper, the mechanical properties of the investigated material couple will be presented. As a first step, the diffusion profiles after different heat treatments were determined by means of electron probe microanalysis (EPMA) investigations. They provide an insight into the quantitative (line-scans) and qualitative (element-distribution mapping) local chemical composition in the interface region. In the second stage, the diffusion coefficients and activation energies were calculated based on the EPMA results. Finally, the observed interface layers were characterized by means of LOM and SEM pictures which were correlated to the EPMA line-scan results.

“…Comparing with in coarse grain sample, diffusion distances of Fe and Ti in the sample with nanostructured microstructures are increased aggressively. Literature 18) shows the diffusion distance of Fe atom in coarse grain titanium alloy sample is only about 10 mm when Ti-4Al-2V and 0Cr18Ni9Ti was bonded for 30 min at 875°C and 8 MPa, at © 2008 ISIJ Table 3.
